  • Patent number: 12002750
    Abstract: An interconnect structure is provided. The interconnect structure includes a first metal line and a second metal line surrounded by a first dielectric layer, a dielectric block over a portion of the first dielectric layer between the first metal line and the second metal line, and a second dielectric layer over the dielectric block, the first metal line and the second metal line. A bottom surface of the second dielectric layer is lower than a top surface of the dielectric block. The interconnect structure also includes a first via surrounded by the second dielectric layer and electrically connected to the first metal line.

  • Patent number: 11990400
    Abstract: Some embodiments relate to a method for forming an integrated chip, the method includes forming a first conductive wire and a second conductive wire over a substrate. A dielectric structure is formed laterally between the first conductive wire and the second conductive wire. The dielectric structure comprises a first dielectric liner, a dielectric layer disposed between opposing sidewalls of the first dielectric liner, and a void between an upper surface of the first dielectric liner and a lower surface of the dielectric layer. A dielectric capping layer is formed along an upper surface of the dielectric structure. Sidewalls of the dielectric capping layer are aligned with sidewalls of the dielectric structure.

  • Publication number: 20240136221
    Abstract: In some embodiments, the present disclosure relates to an integrated chip. The integrated chip may comprise a first metal line disposed over a substrate. A via may be disposed directly over a top of the first metal line and the via may comprise a first lower surface and a second lower surface above the first lower surface. A first dielectric structure may be disposed laterally adjacent to the first metal line and may be disposed along a sidewall of the first metal line. A first protective etch-stop structure may be disposed directly over a top of the first dielectric structure and the first protective etch-stop structure may vertically separate the second lower surface of the via from the top of the first dielectric structure.

  • Patent number: 11935783
    Abstract: Examples of an integrated circuit with an interconnect structure and a method for forming the integrated circuit are provided herein. In some examples, the method includes receiving a workpiece that includes a substrate and an interconnect structure. The interconnect structure includes a first conductive feature disposed within a first inter-level dielectric layer. A blocking layer is selectively formed on the first conductive feature without forming the blocking layer on the first inter-level dielectric layer. An alignment feature is selectively formed on the first inter-level dielectric layer without forming the alignment feature on the blocking layer. The blocking layer is removed from the first conductive feature, and a second inter-level dielectric layer is formed on the alignment feature and on the first conductive feature. The second inter-level dielectric layer is patterned to define a recess for a second conductive feature, and the second conductive feature is formed within the recess.

  • Patent number: 4202514
    Abstract: The present invention is an improved jack device which comprises mainly a jack body, a plunger pump, a base seat and an oil passage device. The outer cylinder of the jack body is made of transparent, semi-transparent plastic material or the like, cylindrical in shape with calibration marked on its wall for indicating oil level, has a soft tube nozzle insetting its wall with a soft tube attached thereto and disposed in the enclosed space of the outer cylinder and is communicable with plunger pump, thereby enabling the reading of the oil amount and the use of the device in inclined positions. Further, the cylinder of the jack body and the cylinder of the plunger pump are formed with base portions by direct forging, are cylindrical in shape and inserted into the corresponding holes of the base seat, firmly fixed on the base seat by welding, making both of them oil-leak proof.
